Does HONOR X30i have fingerprint recognition function

Mobile phone fingerprint unlocking is a function that everyone is familiar with now. In the epidemic environment, fingerprint unlocking is more attractive than facial recognition unlocking. Through fingerprint identification, users can directly unlock by touching their fingers, without using passwords and patterns. Now let's see whether HONOR X30i supports fingerprint recognition.

Does HONOR X30i have fingerprint recognition function

HONOR X30i is not screen fingerprint, but side fingerprint recognition. Its screen material is LCD screen, and it does not support fingerprint recognition under the screen.

The working principle of side fingerprint recognition is the same as that of capacitive fingerprint pressing, which we first used. It is unlocked after the fingerprint sensor and conductive subcutaneous electrolyte form an electric field.

Because our fingerprints are actually not smooth, but composed of undulating textures. When we press the fingerprint identification module, the height of the fingerprint details will form a charge difference. At this time, the fingerprint sensor will record the charge difference to form a complete fingerprint pattern, and compare it with the previously recorded fingerprints to complete the unlocking.

The HONOR X30i uses side fingerprint identification. Although it is not as cool as offline fingerprint identification, it is actually more convenient to use, because it is difficult to identify when you stick a film on the screen, but you don't need to worry about such problems on the side.
